COMBINED F IT TING FOR CLOSETS AND SINKS- Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed October 17, 1904. Serial No. 228,741.

To all whom it may concern:

Be it known that 1, JOHN L. FRUIN, a citizen of the United States, and a resident of Brooklyn borough, New York city, State of New York, have invented certain new and useful Improvements in Combination-Fittings for Closets and Sinks, of which the following is a specification.

My invention relates to that class of plumbers fittings which is used to establish a reventing connection between the main waste and the main vent. Sometimes this connection is made by a simple structure, commonly known as a revent; and the object of my invention is to enlarge the capacity of a revent, make it more positive and powerful in its action, enable it to revent individually a number of articles, and so to construct the fitting that whatever rust forms in the vent will fall back into the waste-pipe and be carried away with the matter passing through said waste-pipe.

My invention therefore consists in a combination-fitting for closets and sinks which is composed of a straight body portion adapted to form part of a main vent-pipe, a downwardly-inclined lateral extension, and two or more vertical pipes of suilicient length to create an efl'ective draft forreventingpurposes, one of said vertical pipes serving as a revent for a closet and another of said vertical pipes being provided with a branch pipe adapted for connection with the dischargepipe of a sink, bath-tub, or washbasin.

In the accompanying drawings I have shown four types of my improved combination-fitting.

Figure 1 shows the fitting when intended for use as an intermediate length of the main vent-pipe and with a lateral hubfor connection with an auxiliary vent. Fig. 2 shows the same adapted for application to the lower end of the main vent-pipe. Fig. 3 is the same as Fig. 1 without the side hub. Fig. 4 is the same as Fig. 2 without the side hub.

Same letters indicate similar parts in the different figures.

A is the body portion, provided with the hub a, and it may also have the side hub b. This body portion is intended to form an integral part of a main vent-pipe, v(not shown,) either serving as an intermediate length when of the form of Figs. 1 and 3 or as the bottom termination. of the main vent-pipe when in the form shown in Figs. 2 and 4.

B is a downwardly-inclined lateral pipe leading from the body A at such an angle as to afford no resting-place for dirt, dust, or other deposit and terminating in a number of vertical pipes C D, corresponding to the number of articles-such as closet-bowls, sinks, washbasins, or bathtubswhich are to be individually as well as collectively vented.

The vent-pipe C is adapted and intended for connection with that part of the main waste-pipe which receives the discharge from acloset-bowl, and therefore does not require any side opening. The vent-pipe D is intended to connect with the main waste, but to serve as a combined waste and vent, and therefore is provided with a side hubbed branch 0, by means of which connection can be made with a dischargepipe of a sink, bath-tub, washbasin, or similar article. This pipe D therefore serves throughout its entire length as an additional vent for the main waste-pipe and everything connected therewith and for that portion of its length below the hub c as a wastepipe for the devices connected with said hub, while the upper portion serves as an individual vent for the same. If more individual venting is required, additional vertical pipes would be provided opening out of the pipe B. This entire fitting is.

intended to lie within the wall of the building, except the hubbed branch 0, which projects through the wall, so as to be easy of access. It will be readily understood, therefore, that when this combination-iitting is set up a permanent and effective venting from the main waste to the main vent is secured at all times, while the pipes entering and discharging through the main waste from a sink, closet-bowl, or other article on each floor of the building may be individually or collectively discharged and vented without any danger of the discharge from one interfering with the venting of another or the venting of one siphoning out the trap of another.

I claim- A combination-fitting for closets and sinks which consists of a body portion adapted to form part of a main vent-pipe, a down- Wardly-inclined lateral extension thereof and length, whereby said pipe is adapted to serve a number of vertical pipes opening clownas a combined Waste and vent for a sink bath- Wardly therefrom of sufiicient length to cretub or Washbasin.

ate an effective draft for reventing purposes; JOHN L. FRUIN. 5 one of said vertical pipes serving as a revent Witnesses: r
